MTG Salvation

I recently had a trade deal with my cousin and he told me to "invest". I gave him about 100 or something cards and I received nothing. But he told me to make a wishlist of about 200 cards and he would try to get them for me by christmas. I am somewhat new to magic. I would like to know any decks, interesting cards, or combos that you would recommend me to ask him for. Currently I love playing aggro, creature, and token dekcs. White and red are my favorite colors. But I am interested in buying green and dark cards. I am interested into ally, vampire, soldiers, hydras, cats, and life gain decks. Recommend me your best!
